High-resolution CPW fabricated by silver inkjet printing on selectively treated substrate

Driven by the development of new functional inks, inkjet-printed electronics has achieved several milestones upon moving from the integration of simple electronic elements (e.g., temperature and pressure sensors, RFID antennas, etc.) to high-tech applications (e.g. in optoelectronics, energy storage and harvesting, medical diagnosis). Currently, inkjet printing techniques are limited by spatial resolution higher than several micrometers, which sets a redhibitorythreshold for miniaturization and for many applications that require the controlled organization of constituents at the nanometer scale. In this Review, we present the physico-chemical concepts and the equipment constraints underpinning the resolution limit of inkjet printing and describe the contributions from molecular, supramolecular, and nanomaterials-based approaches for their circumvention. Based on these considerations, we propose future trajectories for improving inkjet-printing resolution that will be driven and supported by breakthroughs coming from chemistry. Please check all text carefully as extensive language polishing was necessary. Title ok? Yes

“…The combination of chemical grafting methods and plasma or UV-ozone radiation can be used to develop methods for substrate microtexturing for inkjet printing applications (Figure 8). Lee et al [165] and later Kim et al [166] improved silver pattern resolution by exposing spin-coated fluorocarbon films to oxygen plasma. Depending on the conditions of plasma exposure (duration, power), the fluorocarbon layer is degraded and the hydrophilic/hydrophobic character of the substrate can be modulated.…”

“…Generally, when we apply inkjet printing technology to fabrication of metal grid electrode, the fabrication process is simplified by directly-patterning of Ag nanoparticle and sintering. But, inkjet printing has limits to feature size and resolution due to nozzle size, jetting volume and ink spread [8,9]. For these reasons, it is difficult to apply an electrode-printing method to devices such as organic light emitting diodes (OLEDs), solar cells, thin film transistors, and radiofrequency identifications (RFID) requiring precision of 20 m or less [10].…”

This study introduces the novel fabrication of auxiliary electrodes using silver (Ag) inkjet printing for OLED lighting. Generally, inkjet printing has limits to feature size and resolution due to nozzle size, jetting volume and ink spread. To fabricate narrow auxiliary electrodes, this study introduces a unique line width control method using a hydrophilic track formed by spreading barriers. The grid‐like auxiliary electrodes were fabricated by directly‐patterning of Ag conductive line and insulator. The most densely fabricated grid electrode has the line width of 18 µm, the space distance of 0.15 mm. For the feasibility test of the developed grid‐like auxiliary electrode, we fabricated OLED lighting using ITO electrode substrates printed with the grid‐like auxiliary electrode.
